https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D234055 Bug ID: 234055 Summary: PL011 UART driver unable to change baudrate when booted via u-boot Product: Base System Version: CURRENT Hardware: arm64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: arm Assignee: freebsd-arm@FreeBSD.org Reporter: sjorge+signup@blackdot.be After a long few months trying to figure this out... It looks like the PL011 UART driver is unable to set a baudrate when booted= via u-boot. My understanding of the code is poor but it looks like it only works for x86 BIOS/EFI booted systems. This seems like something that might be useful for people running HAT's on raspberry pi's or other ARM boards. Currently the baudrate can be set using u-boot by adding init_baudrate=3D"9600" to /boot/msdos/config.txt but it FreeBSD is unable to change it.=20 It would be nice to have baudrate setting implemented eventually... but at least now there is a ticket for other people having this problem. --=20 You are receiving this mail because: You are the assignee for the bug.=
